Cntn'erdly ot the ends i tie cylindrical portieri et the shaft, the lett i tz pers as at ll to dei-ease in diameter t( Ward its extremity, and it will he apparent that the thickness et' the Wells et the tapered portions ine-reuse toward their outer ex 'reinities Iiitegral gndgeons l2 are formed at the ends of Serial No. 229,144.

the sl'izii'ft, these gniqeons being cylindrical es shown, ind having walls ot substantiel thickness adapted to withstand the strains to which they are subjected. A relatively thick portie-ii is irre red it the inner end et er ch giidgeon. forming' a slioiilcer l- :ind :i ring siirreniids the thielieiied portion lil and may he secured thereto by shriiiing'9 welding eiiy other suitable .munis The enter hice i earch ring obviens y flush with the ridgecent shoulder let..

A linb indicated es :i whole by A(5 is depted teisnrronnd the shfiit'." cent eieh end thereof, erich liiih prerei'zibl' ing octzigonal, es shown in liligjnre 2. hn ii is termed oE :i pair ot conn lenient: ry seezire secured to the sl ett by be ind te erich other by bolts 19. The oi )ortiens the hub are provided with si 'i openings 2O to receive belts hy ineens o eh the siliones or arms or the Wheels nrscc ircd thereto. rEhe hubs illustrated ind eeseribed are ot the usuel tyge and torn n pei-t oit the present invention.

rlhe eneriition of the device is es follows:

in the iiiziniite-.ctnre ot the device7 n section cit tiihnlsr steel stock employed and the i s i l' this section are reduced hy sivaging in several operations te form the tapered portions l1, gndeeons l2 and shoulders 13. It will be apparent that as the diameter of the body of the device decreases7 the thickness of the Wells theree'f vill be materially increased, yhns adapting the structure to withstand heavy sti-:zins et the bearing engaging 'pon tions thereof.

n iissen'iblingv tie struct-nre, the hub seovions l? fire bolted iii position in the usual iiiziniier. zitter which the spokes or erms are secured zit their inner endl :igziiiist the trices the hub :ind are belted thereto in the iisnzii iiizinner. lhe rims :ire then secured to the ter ends ot the spokes. es will he apparent.

be taken as a prelierred example el the same and that various changes in the shape, size and arrangement oit parts may be resorted to without departing 'from the spirit oi the invention or the scope et the subjoined claims.

Having thus described my invention, l claim:

l. A device of the character described coinprising an integral body including a central elongated tubular shaft section, and relatively thick inwardly swaged reduced gudgeons at the end portions thereof.

2. A device the character described coinprising an integral body including a central elongated tubular sha'l't section, inwardly swaged tapered portions extending beyond said shalt section coaxial therewith, said gortions decreasing` in diameter toward their outer end-s, and swaged relatively thick reduced gudg'eens extending beyond the ends oit' said tapered portions.

3. A device ot Vthe character described co1nprising an integral body including a central elongated tubular shatt section, inwardly swaged tapered portions extending beyond said shaft section coaxial therewith, said portions decreasing in diameter toward their outer ends, and swaged relatively thick reduced gudgeons extending; beyond the ends of said tapered portions, the outer ends ot' the tapered portions being provided with annular shoulders slightly larger in diameter than and defining the inner entreinities of said gndgeons and forming bearing,` engaging` thrust faces.

4r. A device of the character described coinprising an integral body including a central elongated tubular shaft section, inwardly swaged tapered portions extending beyond said shaft section coaxial therewith, said port' ne decreasing in diameter toward their outer ends, and swagod relatively thick reduced gudgeons extending` beyond the ends ot said tapered portions, the outer ends of the vtapered portions being provided with annular shoulders slightly larger in diameter than and definingl the inner extremities et said tqudgeons, and separate rings surrounding said body and secured thereto, the outer faces o said rings beingv flush with said shoulders and forming therewith bearing` engaging thrust faces.

5. A device o't the character described coniprising an integral body including a central elongated relatively thin tubular shaft section, inwardly swaged tapered portions en* toning beyond said sha'tt section coaxial therewith, said portions decreasing,` in diameter and increasing in thickness toward their outer' ends, and swaged relatively thick reduced gudgeons extending beyond the ends of said tapered portions, the ends ot said tapered portions being` substantially equal in thickness to the adjacent portions ol" said eentral section and said gudg'eons respectively, the enter ends ci said tapered portions being` provided with annular shoulders slightly 1ger in diameter than and defining' the inner e1 ren'iit'es of said gudgeons, and separate rings surroundingV said body and secured thereto, the outer faces of said rings being flush with said shoulders and forming therewith bearingl engaging thrust laces.
